3 | // This is a class that constructs AliFMDRecPoint objects from of Digits | |
4 | // This class reads either digits from a TClonesArray or raw data from | |
5 | // a DDL file (or similar), and stores the read ADC counts in an | |
6 | // internal cache (fAdcs). The rec-points are made via the naiive | |
7 | // method. | |
